/Engine/Source/Runtime/Landscape/Classes/LandscapePhysicalMaterial.h
A single task for calculating the landscape physical material. The work uses the GPU so this object handles reading back the data without stalling. We need to callTick()untilIsComplete()returns true. We need to callRelease()after use to prevent leaking of internal objects. All calls are expected to be made on the game thread only.
